The perimeter of a rectangle is 44 centimeters. If the length is 10 centimeters, find the value.
lukranit [14]

Answer:

12 cm is the width

Step-by-step explanation:

The perimeter of a rectangle is given by

P = 2(l+w)

We know the perimeter is 44 and the length is 10

44 = 2 (10+w)

Divide each side by 2

44/2 = 2/2 (10+w)

22 = 10+w

Subtract 10 from each side

22-10 = 10-10 +w

12 = w

The width is 12

Find the measure of line f and g
kiruha [24]

In this case we use intersecting secant theorem  

According to this theorem, GF*GE = GH*GA

So,we plug in the values

(x-3)*(x-3+9) =(x-2)*(x-2+6)

(x-3)*(x+6) =(x-2)*(x+4)

x^2 +6x -3x -18 =x^2 +4x -2x -8

x^2 +3x -18 =x^2 +2x -8

x^2 +3x -18 -x^2 -2x +8 =0

x -10 =0

x=10

So,FG =x-3 = 10-3 =7

PLEASE HELP! IM A MONTH BEHIND IN MATH AND FREAKING OUT T^T PLZZZZ
ANTONII [103]
A) Let x stand for time, y stand for velocity.
We are given the points (2,50), (6, 54). We can make a line using the slope intercept form
y = mx + b.
slope is (54 - 50)/(6-2)  = 4/4 = 1
y = 1x + b
plug in point (2,50) to find b
50 = 1(2) + b
50-2 = b
48 = b
the equation is  y = 1x + 48
Make standard form.
<span>x - y = -48
</span><span>b) make a table and plot points for the first 7 hours
Table Is attached.
Good Luck!
If you like the answer please give me brainliest answer!
